Fire Testing – IEC 60332 • IEC 60332 - Vertical Flame Propagation

• Parts 1 & 2 - Specifies test methods for

vertical flame spread of a single insulated wire or cable

• It is not recommended that compliance to this standard alone is sufficient to demonstrate the cables ability to limit flame spread.

Bunched cables will most likely behave differently. See IEC 60332-3.

3

IEC 60332 – Part 1 & 2 Part 1 • 1KW flame intended for general use • Flame duration varies from 60 – 480 • seconds and is dependent on diameter • Char height must be between 50 and 540 mm from lower edge

of top support • Filter paper under burner must not ignite from flaming droplets Part 2 • Diffused flame intended for small diameters less than 0.5mm2 • Flame duration is 20 seconds maximum or 2 seconds less than

melt time • Char height must be between 50 and 540 mm from lower edge

of top support

IEC 60332 – Part 3 • Part 3 - Specifies test methods for vertical

flame spread of bunched cables • This part of the standard is most often

referred to when flame propagation is of concern. The different categories are used to demonstrate the cables ability to limit flame spread.

• Category A is the most difficult to achieve because the cable loading is the heaviest.

IEC 60332 – Part 3 Cat A,B,C 60332-3-22 Category A Cables bunched on test ladder to achieve a non-metallic volume of 7 l/m Flame duration is 40 minutes Char height must be less than 2.5 m from bottom edge of burner 60332-3-23 Category B Cables bunched on test ladder to achieve a non-metallic volume of 3.5 l/m Flame duration is 40 minutes Char height must be less than 2.5 m from bottom edge of burner 60332-3-24 Category C Cables bunched on test ladder to achieve a non-metallic volume of 1.5 l/m Flame duration is 20 minutes Char height must be less than 2.5 m from bottom edge of burner

Fire Testing - IEC 60331

• IEC 60331 - Specifies test methods for circuit integrity cables under fire conditions

• This test is a horizontal flame test of an energized cable. The standard is broken down into four parts depending on type of cable tested.

7

IEC 60331

• Part 21 - Cables rated up to 600/1,000 volts

• Part 22 - Cables rated greater than 1,000 volts

• Part 23 - Electric data cables • Part 25 - Optical fiber cables

8

IEC 60331 – Part 21 • Part 21 is applicable to Dekoron's product • Cable is energized to the rated voltage and

has indicator lamp wired for continuity check. • Flame temperature is user specified but 750C

is minimum requirement. • Flame duration is user specified but 90

minutes is usually recommended. • Cable must maintain test voltage without

fuses or circuit breakers being interrupted and indicator lamp must remain on for the specified test duration plus a 15 minute cool down period.

BS 6387 Fire Test Standard

BS 6387 C, S, W & Z Cable maintains circuit integrity for 20 minutes at 950° C and is then subjected to mechanical shock and water spray (sprinkler) with electrical integrity maintained.

Customized Fire Test

• Hydrocarbon Pool Fire Cable to maintain circuit integrity during fire test

that simulated the actual fire condition during fire in refinery or chemical plant in term of fire intensity for 15 minutes
